Yes I searched.

I've noticed a very slight but also very inconsistent vibration when I'm stopped. It occurs whether or not the clutch is engaged, the car is in gear and if the AC or fan is on or off.

Its as if the engine is stalling but you really have to pay attention to notice it at times, Its usually very faint. The RPM gauge does not move (I think) when it happens. Any ideas? Spark plugs maybe?

Its a MT and I never noticed anything like this on my AT.

 

motor mounts?

 

I thought about that as well. But

The vibration on the AT was very consistent, is was always there when stopped so it just bacame part of the car. This is annoying because its smooth and suddeny you feel a very small hiccup. Now that I've been paying very close attention to it, I've noticed it actually happens every 2-5 seconds, some worse than others.

 

I haven't noticed it in my 6MT an I usually have the radio off. Is it a vibration or a sound?

 

Vibration, no sound. I don't think you'd notice it. Definently not a normal or common problem. I'm betting something is wrong.

 

Interesting. Have you been able to corrolate the 2-5 sec. cycle to anything else going on in your car? Perhaps the A/C or the turn signal? My wife's Civic changes the engine tone slightly, keeping time with the hazard lights when they're on. She doesn't have a tach so I don't know if the engine RPMs fluctuate as well. I guess any accessory that cycles power use every 2-5 sec. is a candidate (due to poor ground?)

 

Hmmm, I'm going to look into that further. I've really only fiddiled with the HVAC and radio so far.

Its so strange because it definently feels engine related but there's no movement from the TACH.

 

i've had my CAI in short ram the last few months and noticed increased vibrations...just put it back in full CAI and the vibes are gone. I had a loose nut on the lower vibramount.

 

Stock here...

 

sorry. thought it might help.

 

I have an Injen sitting in the garage. Maybe I'll put in on to see if it fixes it.

 

The weird thing is no movement in the tach. I remember in an 89 honda when the car is at a stop and if you pushed the window up button, when the windows were already up, the rpms would go down slightly.

 

hehe. give it a shot! seriously, when i put it in full CAI, my engine began to run much smoother and without the kinda roughness it has been having lately. also responds better than in SRI. unfortunately, i don't remember the stock response or vibration.

 

I think the USDM accord had a TSB or something for vibration in the engine. I believe the solution was larger counterweights in the engine or something.

 

Ok, I've confirmed the vibrating is directly related to the engine as my RPM's are moving ever so slightly when it vibrates. Yesterday for the first time it dipped significantly. It idles at about 750 but then suddenly dropped to below 500 (felt like it was stalling) and then quickly back up again. Car was in neutral clutch was not engaged and no AC or HVAC was on. I was stopped at a red.

Any ideas? fuel filter maybe? My oil level is fine.

 

i'm gonna say fuel filter or maybe even air filter. Or maybe even ignitions? Is it like the timing is off every once in a while?

 

I guess, although I'm not really sure what timimg being off would feel like. I can relate it best to stalling from 1st gear.

 

Strange thing is, I have sort of the same problem. I'll get a sudden "vibration" but I haven't had time to figure out the cause. It seemed to happen only when stopped at a light and so far it's only happened during A/C use. I'm driving a MT as well.

 

yeah, mine gets sorta rough only with AC on. i told a tech at dealership yesterday and they are gonna give it a run on thursday.

 

Battery dying making the alternater to draw more power?

 

^^ hmmm, that might be.

 

im gonna get a new battery and see what happens. any suggestions?

 

Interesting point. At 82K it very well could be the battery. Thanks. Dealer is picking it up tonight to replace the radio and I've already mentioned this problem so we'll see what they have to say.

 

trade it in for the 5AT!

duh.

 

Don't think I'm not starting to wonder if I made a huge mistake. I'm really hoping this problem is something simple lke the battery or fuel filter.

 

If I have to guess, I would say it's the EVAP purging, part of the emission control process. I have experienced it with other Hondas.

 

Let me guess... It is the famous VANOS issue!

 

Anymore info? Is this bad and why aren't others complaining of the same problem?

 

Same issue here, 06 MT w/1000 miles. Only at idle, regardless if clutch is depressed or not, a/c on or off. The RPMs just ever so faintly drop by 100 or so and shoot right back up. Doesn't happen all the time. Veerd. Let us know what they say.

 

The main purpose of the evap system is to minimize gas vapor escaping into the atmosphere. It consists of vapor flow valve, canister and purge control solenoid. The gas vapor in the gas tank flows through the vapor valve, then to canister. The ECU then sends a signal to the purge solenoid and route the collected vapor from the canister to the intake manifold. I notice the idle usually fluctuate a little when this takes place on my other Hondas.

 

In my '93 Civic, if I depress the brake padal, the computer will lean the gasoline and lower the rpm.

In the TSX, if I try to turn the wheel while the car is stop, the power steeling will draw more power from the engine. So, it will make the rpm lower.

 

This happens as well but this problem is not related.

 

But this is moor or less a consistent vibration that my AT did not have, which is why I'm concerned.

Dealer still has my car, had it since Thursday. Talked to them on Thursday evening and they could not notice any vibrating but did take note of the complaint.

After driving the CSX (Civic) for these last 4 or 5 days I desperatly want my TSX back. Its truly night a day between these 2 cars.

 

So I got my car back last night and they tried to pass off the vibration as the AC or fan turning on which it definently is not. The problem remains and its driving me nuts. My AT did nothing like this ever. I'm trying another dealer.

 

If the problem is consistent, then it should be easy to troubleshoot. I would hook up a scan tool and fire up the data logging and record the various sensor values and their off/on states in relationship to the vibration.

 

Well its not really consistent in the sense that it happens every single time. Put it this way. I'l1 notice it 8 out of 10 times and some times its more severe than others. It was particulary bad this morning but the RPM's weren't budging when it was happening.

I seriously doubt the dealer did anything to be honest. They probly sat in the car didn't feel it so passed it off as nothing.

The main problem here is the dealer I got this car from is about 45 min to an hour away from home. I didn't drop the car of myself so I didn't have the chance to properly explain or show them what was happening. I just got off the phone with my regular dealer and explained the problem. My regular service advisor said he's familar with the problem and its related to the throttle which will require adjustment. Make sense?

I'm going in Saturday morning to have this looked at.

 

I have an 05 AT and it does it. I'll be at a red light and then feel like the car is stalling - look at the RPM and it's at 500. Then it goes right back up.

Let me know if the dealer does fix the problem when you bring yours in.

Mine's going in soon for it's second oil change and I plan on mentioning the problem. I hate to have the car stall someday.

 

So I went to the dealer on Saturday. They ended up "adjusted idle" I wasn't charged and my rep suggested that if this doesn't fix it to leave it with them for the day as the experienced mechanics aren't in on Saturday's. On the drive home the car was fine. I was still feeling the "jumps" but not nearly as bad as I was before. Took out the car breifly on Sunday and it was back. Took it to work this morning and its definently back.

Looks like it will be spending some more time at the dealer.

 

For me, I usually get some vibrations but more so when I'm coasting and sometimes here and then when I'm on the move eg accelerating and braking

Shouldn't really bother me but in a cars like ours, u do sorta expect something like this not to happen ey?

I'm dued for a service soon but yeh definitely get a second opinion head ova to another dealership to poke their head around this one

Btw, how would you check for a faulty engine mount?

Cheers

 

Kind of funny. I've been looking at TSX's for a couple weeks now, and noticed a woman at my dads work has an 06 with like 2k miles on it. She told me I could take it for a spin, and I noticed when I had put it in D it almost seemed as if the car was going to die. I almost made a remark about it but thought maybe it was normal.
